The Ultimate 12" of suspension is what this 2500 GM is sporting.  We installed a 12" Cognito Suspension with FOX Shocks and Cognito Traction bar.  In order to get into this tall truck we also installed AMP Side steps.  We can't forget the wheels and tires which consist of 40x15.5R20 Toyo Open Country Tires and Fuel D588 Wheels.
